Abstract
Abstract A hollow tank body portion (11) is formed by folding a plate of aluminium clad with a brazing filler metal layer (R). One end of the plate material (11a) extends over the other end (11b) and the thus overlapped ends (11a, 11b) are brazed together. Preferably these overlapped portions (11a, 11b) provide a locating portion for a mounting bracket (25 Fig 6) to hold it in place as it is brazed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
58 words
A heat exchanger tank comprising: a hollow tank body portion (11, 20, 21) formed by
folding a plate made of aluminium clad material having a
brazing filler metal layer (R), and wherein a first end
(11a, 20b, 21c) of the plate material extends along and is
brazed to a second end (11b, 20c, 21b) of the plate
material.
Claim 2
Dependent Claim
29 words
A heat exchanger tank according to claim 1, wherein an
outer surface of the tank body portion (11, 20, 21) is clad
with the brazing filler metal layer (R).
Claim 3
Dependent Claim
28 words
A heat exchanger tank according to claim 1 or 2,
wherein an internal surface of the tank portion (11, 20,
21) is clad with a sacrificial layer (G).
Claim 4
Dependent Claim
30 words
A heat exchanger tank according to any one of the
preceding claims, wherein the tank body portion (11, 20,
21) is formed so as to have a rectangular cross section.
Claim 5
Dependent Claim
38 words
A heat exchanger tank according to claim 4, wherein
the first end (20c) and the second end (20b) of the plate
material are overlapped and brazed to each other along an
angular portion of the rectangular cross section.
Claim 6
Dependent Claim
52 words
A heat exchanger tank according to any one of the
preceding claims, wherein a hole (17a) used for mounting an
inlet or outlet pipe (17) to the heat exchanger is formed
in a surface opposite to a surface in which the first end
(11a, 20b, 21c) of the plate material is brazed.
Claim 7
Dependent Claim
78 words
A heat exchanger tank according to any one of the
preceding claims, also including a mount bracket (25) including a main
body (25a) brazed to a mount surface (21a) of the tank
portion (11, 20, 21) and a leg (25b) brazed to a surface
(21b) adjacent the mounting surface (21a); wherein overlapped first and second ends (11a, 20b,
21c; 11b, 20c, 21b) are sandwiched between the main body
(25a) and the leg (25b) of the mount bracket (25).
Claim 8
Dependent Claim
112 words
A heat exchanger tank comprising: a tank body (11, 20b, 21c) formed by folding a plate
material so as to have a rectangular cross section, a first
end of the plate material (11a, 20b, 21c) extending along
an outer side of an adjacent surface of the tank body; and a mount bracket (25) including a main body (25a)
brazed to a mount surface (21a) of adjacent to the adjacent
surface of the tank body and a leg (25b) brazed to the
adjacent surface; wherein the first end extended along the outer side of
the adjacent suface is sandwiched between the main body
(25a) and the leg (24b) of the mount bracket (25).
Claim 9
Dependent Claim
42 words
A heat exchanger tank according to claim 8, wherein
the plate material comprising aluminium clad material, and
a side of the plate material which serves an outer
peripheral surface of the tank body is coated with a
brazing filler metal layer (R).
